Return unwanted prezzies - if you can. Don't like those socks or that Little Mix CD? You don't always have automatic return rights - here's the deal (all explained in our full Xmas Return Rights guide).

Unless faulty, you've no legal right to return goods bought in a store. Many shops allow it though, so ask with a smile, and if it offers something, eg, an exchange or credit note, you're doing well.If bought online, the buyer has more rights. They've up to 14 days from receipt to say they're sending it back and another 14 to return it for a refund or exchange, whether faulty or not. If you're not the buyer you'll almost certainly need to go through them. If faulty, the buyer can return it regardless of where it was bought. Though if you've a gift receipt the rights transfer to you. See the SAD FART definition of fault.
